Very good work Damiano Mazzella, after pulling a lot of hair trying to make another port work - I downloaded your port and it worked great! Thanks

Hi all! Im newbie in OpenGL and I find this port very usefull. Ive been use it for about a week, doing some tests whithout problems. But when I use this code in a more complicated project, it throws some random bugs. This minors bug where solved when I initialize these variables in class PRFilledPolygon class:
int areaTrianglePointCount;
CCTexture2D texture;
CCPointareaTrianglePoints;
CCPoint textureCoordinates;
PRRatcliffTriangulator triangulator;
To solve it I made a constructor directly in PRFilledPolygon.h:
PRFilledPolygon() {
areaTrianglePointCount = 0;
texture = NULL;
areaTrianglePoints = NULL;
textureCoordinates = NULL;
triangulator = NULL;
}
You can initialize the variables wherever you want.
Thanks again!

Hello,sir! i write my code like this:
@
texture = CCTextureCache::sharedTextureCache()>addImage;>getLocationInView();
void HelloWorld::ccTouchMoved
{
//CCPoint test = pTouch
CCPoint test = pTouch~~>getLocation;
//points.push_back);
vc.push_back);
CCLog;
}
PRFilledPolygon *temp = PRFilledPolygon::filledPolygonWithPointsAndTexture;
@
but the program will crash at
`void PRFilledPolygon::setTexture(CCTexture2D* texture2D) {
CCAssert(texture2D, `“NO TEXTURE SET”);
CC_SAFE_RELEASE;//crash at this line
texture = texture2D;
CC_SAFE_RETAIN;
ccTexParams texParams = { GL_NEAREST, GL_NEAREST, GL_REPEAT, GL_REPEAT };
texture~~>setTexParameters(&texParams);
updateBlendFunc();
calculateTextureCoordinates();
}

I don’t know why. can you help me ? i use cocos2d-x 2.0.4 Thank you

I think this error its beacuse the texture, you load in the cache, was released by cocos2dx in some moment before want to use it inPRFilledPolygon::filledPolygonWithPointsAndTexture(vc, texture);. Cocos2dx release it, but you still have a pointer to that texture, the when PRFilledPolygon wants to release some thing already released, it crash.
A possible solution, if it was the case, should be putting**CC_SAFE_RETAIN(texture);* after the line texture = CCTextureCache::sharedTextureCache->addImage; to prevent that cocos2dx dispose. And maybe, somewere, do a CC_SAFE_RELEASE; after you use it or in the destructor of that class. Hope this work.

Hello,sir. thank you for your reply. but it also crash at that line , i write this:
texture = CCTextureCache::sharedTextureCache()->addImage("HelloWorld.png"); CC_SAFE_RETAIN(texture);
please help me
can you give me your code …….you said you use it smoothly. thank you
Thank you for share. it work normal now . i add some code:
PRFilledPolygon()
{
texture = NULL;
areaTrianglePoints = NULL;
textureCoordinates = NULL;
triangulator = NULL;
}
haha

My code its exactly the same as the posted here by Damiano Mazzella, except for the fix that I posted, tho one that initialize the variables. Every thing works great. Ive been use it for two month without any problem. I think I get confused and doesnt understand right your error, but using retain and release is something to care about.

Hello, sir. i want to save the lastest texture, how can i do ?

Hi qiujie tian,
if you want to save in a file you could use CCRenderTexture.
bool saveToFile (const char *name, tCCImageFormat format)
saves the texture into a file.

D.
Hi all, I just created a repository on github, you can find it at this link: git://github.com/dmazzella/cocos2d-x-PRKit.git
